ENT - Level 1 Flashcards
Definition of otitis media?
- Middle ear inflammation
Definition of recurrent otitis media with effusion?
- Recurrent ear infections – secretory otitis media (Glue ear)
Middle ear effusion without the symptoms of acute otitis media
How common is otitis media?
o Bacterial (most commonly)
Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, streptococcus pyogenes
o Viral
RSV, rhinovirus, adenovirus, influenza and parainfluenza
Causative organisms of otitis media?
o Bacterial (most commonly)
Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, streptococcus pyogenes
o Viral
RSV, rhinovirus, adenovirus, influenza and parainfluenza
Symptoms of otitis media?
- May follow URTI
- Symptoms
o Rapid onset pain in the ear
o Fever
o Irritability
o Vomiting
o Deafness
Signs of otitis media?
o Bright red and bulging with loss of normal light reflection
o Occasional acute perforation with pus in ear canal
o Look for swelling over mastoid – mastoiditis secondary
Diagnosis of acute otitis media?
o Acute onset – earache, holding, tugging ear or non-specific symptoms
o Otoscopy – red, tallow or cloudy tympanic membrane with bulging and loss of normal landmarks, air fluid level behind tympanic membrane or perforation
When to admit of otitis media for specialist assessment from primary care?
o Severe systemic infection
o Acute complications of otitis media (meningitis, mastoiditis, incracranial abscess, sinus thrombosis, facial nerve paralysis)
o Child <3 months with temperature >38
Management of otitis media - general advice?
o Analgesia (regular paracetamol and ibuprofen) o Most cases resolve spontaneously within 3 days but can be up to 1 week
Management of otitis media - antibiotics?
o If very unwell, have symptoms and signs of illness or high risk:
Immediate antibiotic
o For those who may benefit from antibiotics, consider delayed prescription, no prescription or immediate
Amoxicillin for 5-7 days
Can give clarithromycin or erythromycin if penicillin allergic
Management of otitis media - if perforation?
o Follow up with ENT and do not swim
Management of otitis media - if treatment failure?
o If not taken antibiotic – give prescription
Amoxicillin for 5-7 days
Can give clarithromycin or erythromycin if penicillin allergic
o If taken first-line antibiotics, give co-amoxiclav for 5-7 days
o If symptoms persist despite two courses of antibiotics – refer to ENT
Management of otitis media if persistent symptoms - hearing loss with no pain or fever?
Active observation for 6-12 weeks
Two hearing tests using pure tone audiometry >3 months apart
Management of otitis media if persistent symptoms - hearing loss with no pain or fever - when to refer?
o Hearing loss impacting child development
o Hearing loss >61dB
o Significant hearing loss on two occasions
o Tympanic membrane abnormal
o Foul-smelling discharge (cholesteatoma)
o Down’s syndrome or cleft palate
Management of otitis media if persistent symptoms - hearing loss with no pain or fever - non-surgical and surgical management?
o Active observation for 3 months with regular audiology follow up
o Hearing aids
o Autoinflation
o Myringotomy with Grommet insertion, with or without adenoidectomy
If persistent bilateral OME over 3 months with hearing in better ear <25-30dB averaged at 0.5, 1, 2 and 4 kHz or if affecting development
Adenoidectomy only if frequent URTIs
Follow up until grommets extruded and eardrum healed
Management of otitis media if persistent symptoms - discharge from ear canal for 2 weeks?
Refer to ENT assessment – given steroids and antibiotics and intensive cleaning of ear
Complications of otitis media?
- Mastoiditis
- Meningitis
Definition of pharyngitis?
local inflammation of oropharynx with enlarged and tender lymph nodes
Definition of tonsilitis?
form of pharyngitis where there is intense inflammation of the tonsils, often with purulent exudate
Definition of influenza?
acute respiratory illness caused by RNA Orthomyxoviridae viruses
Epidemiology of URTIs?
- Highest incidence in children and young adults
- More common in winter
- URTI are 80% of respiratory infections
Causative organisms of common cold (coryza)?
Rhinovirus, coronaviruses, influenza virus, parainfluenza and RSV (however RSV usually causes acute bronchiolitis)
Lasts 1 ½ weeks
Common – adults 2-3x colds per year, children 5-6x colds per year
Causative organisms of Pharyngitis/tonsilits?
Adenoviruses, enteroviruses, rhinoviruses, influenza types A and B, parainfluenza, group A B-haemolytic streptococcus, HSV-1, EBV, Candida
Non-infectious – physical irritation, hayfever, GORD, Kawasaki’s disease, oral mucositis
Lasts 1 week
Causative organisms of epiglottitis?
Hib
Causative organisms of influenza?
Type A – frequent and more virulent, local outbreaks and epidemics
Type B – co-circulates with A during yearly outbreaks, less severe
Type C – mild/asymptomatic infection similar to common cold
Peak during winter months
Symptoms of tonsillitis/pharyngitis?

Coryza, cough, fever, Diarrhoea, headache, myalgia, malaise, sore throat, photophobia, conjunctivitis
Symptoms of complicated influenza?
Signs and symptoms requiring hospital admission, LRTIs, CNS involvement, exacerbation of underlying medical condition
Assessment of tonsillitis/pharyngitis?
o Clinical examination – pus on tonsils indicates bacterial infection
o Neck – think bacterial infection if tender lymphadenopathy
o FeverPAIN score
o Centor Criteria
What is FeverPain score in tonsillitis?
Fever >38 Purulent (exudate on tonsils/pharyngeal) Attend rapidly (<3 days) Inflamed tonsils No cough/coryza • Score 4 or 5 - Abx
What is Centor Criteria in tonsillitis?
Tonsilllar exudate Tender anterior cervical lymphadenopathy Fever Absence of cough • 3 or 4 needs Abx
